'Th'eyohedule referredto in these Letters Patent'and making parl: of the name.V y y it4 aannam-tm@ comme ,n Be known'that I,\WILL1A`M H. SM1TH, of Netw y York city, in `theState of VNew York, have invented certain new land -uscful Improvements in Ornamentl `lowing isa full andexact descriptionthereof. n My machine is intended moreJ particularly for grain-'r `withthe previous machines, when operating in sunk',y i panels, tou'emove' the machines, and discontinue the y lbeen `possible with machines Apreviously ing in imitation of wood, applying coloringmatter by n' means of a `soft surface, properly engraved, or indented, Aso as to imitate the coloring, and also their-regular bgnres of diiierent` varieties of wood; but it maybe used to ornament, by means `of other colors, and by l the use of sulfacesiotherwise engrayed or prepared, so

as to produce scrollwork,.lettering, or even pictures.

y `My invention" adapts the machinesV to workyunder conditions, and to ornament in `places which have not i If.

willfor example, ornamentsnnk` panels,

` in analogous situations, and produce the''ornamental'` `effect quite `up to the end of each,"it beingnecessary ornament `at a considerable distancefrom vthe ends of thepanels, leaving the ends of the panels blank, or

l n Vunornamented.

I .willlir'st describe what Iconsider `.the best means of carrying `out my invention, and will afterward des- Y,

n ,f'lignate the points which l believe to be new.

The accompanying drawings form .a part of this j specification. K fc Figure 1 is a side elevation, and

Figure 2,"an-end elevation ofmy machine for orna-V menting. i

Figure 3 is an edge yiew'ofa portion of the en?d graved elastic belt, or band, H, on an enlarged scale, showing the relationthereof to thc man'cylinder, and

"also to the small roller, "which is employed underthe n belt, as represented. i n v n n Similar' lettersof reference indicate like parts in all the figures. L y A` is the `ixedwlra1ne`work, provided with handles, a a. 'lhisame-work forms the bearings Vfor all the aparts.` n w n l. Ahollow shaft, "B, is mounted in .thisV frame-work, with liberty to turn. i

'lhe' hollow shaft isclosed at one` end, and is pro- `vided at the other with a screw-plug, which allows the'blowing' up of the elastic cylinder: C,which is mountedlon `the shaft B, as`represeu\ted.` n n n All these parts may be Yconstructed, in the manner described in the patent issued to Robert A. Adams, `dated z I) and E are hiking-rollers, or coloring-rollers, which n may be adjusted in the machine as `represented,aud

i which applytthe coloring-matter uniformly,

as will be readily understood.

nemici rellene, amounted `in bea-ings in the L `frame A, as represented.-h It `is of small size, being, `in practice, only from one-.fourth to three-eighths of 1 I a sunk panell an inch in diameter, wit-h bearings turned smaller, so i as to offer very `little friction. This is mounted relatively to theflarge cylinder C, as represented. g n H h is an elastic belt, running over both the large ing-Machines; and AI do hereby declare that th'fdblcylinder C and the small cylinder, or roller G.-

. Its outer surface iscomposed of a soft composition, -which Amay be glue and molasses, boiled together', orlany of the analogous compositions, which Will give a 'highly elastic surface; It is engraved, or indented, as before suggested, to produce the ornamental design required. n n p l Its'iuner surface isfcomposed of knit woollen yarn,

as indicated by h, the outer Vsurface Vbeing designated u This knit surface gives a strength to thebelt which o peculiarly fits it for the it is used. Y n

The machine is applied to the work in the same manner as is'describedin the Adams patent, before referred to, and is rolled forward,` on plain surfaces, in the same manner, the belt H h rolling around the cylinder O, and traversing .over the small roller G, as will difficult conditions under which be understood. A v l l The peculiar properties of the machine become avail- `able when it is desired to ornament close tothe end of To do this, the machine is heldin such part of the l the roller G is pressed upon f i position, at each end of the panel, that that belt which is resting on the surface `to be ornameuted.

The small diameter of the roller Gr allows it, and. the belt covering it, to tit very closely'intothe ends of the sunk panels.` v

It will' now be understood `that,fin commencing at one end to ornament a sunk panel, the machine is applied at the extreme end of the panel, pressing upon the work with that part of the belt whichvlies on the small roller-G. In this position it is moved forward,

andthe belt Hh, and its connections,` turn gradually as the machiues moved. After having thus moved e away from the end of the panel, the portion of thebelt 'which rests upon the large cylinder C maybe-made available, andin this condition the beltwill apply with more elastic action, because the elasticity of the air in the cylinder C becomes available, to aid'iu applyl Y ing the oruamenting-surface `t0 the iuequalitiesin the f panel.

machine is again. tilted np into the position so that the pressure is effected through 'the small roller-G,

instead of through the large roller O. f

,. In order toproduce thel belt,the knit goods h having been previously made of `a proper size, and cut or otherwise prepared in proper lengths, are held on a mould, .which iscollapsihlqaud being'placed within another mould, so as Vto leave a-proper thickness for the composition, the melted composition is poured in,

and allowed to illthe space, and also to saturate the vi'nterstices in the knit material h.

After the composition has set and lsuiiciently hard- On approaching' the opposite` end of the panel, the o ened, the interior of the mould is collapsed, and thel compound belt thus produced is carefully removed.

When properly hardened, this belt; may be applied to the machine, as before described, and may be used for a. longer period,

The knit lining h performs a very important function, Yin rgiving strength and durability to the belts. Without this expedient, or some equivalent therefor, I believe it would be impraetioable to run a sufficiently soft and elastic belt over the small roller G in the mam ner described.

Having now fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is as follows:

roller, O, and witgh an operating-frame, A (o, or its equivalent), so as to ornement thereby, not only on plain surfaces, butin recesses, or rentering angles in the work,

"subtantially as and for the purposes herein ser; forth.
